Upper Fornix Approach to the Superonasal Intraconal Space: An Experience Including a Pediatric Patient.

In this study, we present 2 patients, including 1 pediatric patient, with orbital tumors in the deep superonasal intraconal space, which were approached with upper fornix technique combined with a superior lateral cantholysis. The first patient was a 1-year-old girl who had presented with left upper eyelid retraction since the age of 2 months. Imaging studies revealed an orbital mass in the left postero-superonasal intraconal space. The second patient was a 71-year-old man who complained of decreased vision after cataract surgery in the left eye. Imaging studies revealed an orbital mass in the left superonasal intraconal space surrounding the optic nerve in the posterior orbit. In both the patients, incisional biopsy of the orbital mass with upper fornix approach was performed under general anesthesia. The diagnoses of congenital upper eyelid retraction caused by fibrosis in patient #1 and extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue in patient #2 were made, after pathological examinations. No significant intra- or postoperative complications occurred during a follow-up period of 10 months and 2 months, respectively.
